Left: virial parameter versus core mass. The dashed line indicates the virial equilibrium limit (α_vir = 1), and the dash-dotted line shows the limit of gravitational boundedness (α_vir = 2). Right: ratio of 3D velocity dispersion to escape velocity against core mass. The dashed line indicates σ_3D/v_esc = 1. All cores are likely to be gravitationally bound. The solid line in both plots indicates the least-squares fit to the data. Both plots are in log-log scales, and the symbol key is identical to that of Fig. 4.
